Every solar power plant is a fusion power plant with extra steps.
Nearly every power plant is a solar power plant with extra steps.
I think using solar to harness the Sun's fusion actually has fewer steps than a fusion plant would because a fusion plant would use the EM radiation to boil steam to push turbines to turn a generator to move charge carriers.
A solar cell uses the Sun's fusion EM radiation to knock electrons onto a wire and move them along.
But we'll probably need both anyway to get away from that dirty oil.
